Description
Laretol Injection is a form of vitamin D3. It is used in the treatment of calcium deficiency in people having hypocalcemia (a condition with low calcium levels in the blood), hyperparathyroidism (abnormal production of parathyroid hormone), and secondary hyperparathyroidism (overproduction of parathyroid hormone). Laretol Injection is also used to treat renal osteodystrophy (skeletal abnormalities occurring in people with severe kidney problems) and Postmenopausal osteoporosis (a bone condition causing weak and brittle bones that develops after menopause in women). It helps in regulating the absorption of calcium and its utilization in the body. Laretol Injection may cause side effects like headache, abdominal pain, increased calcium levels, skin rash, nausea and vomiting. These side effects may subside over time. Consult your doctor if any other side effects occur or persist for a long period. Avoid using Laretol Injection if you are allergic to it. Laretol Injection is a prescription medicine available as a soft gelatin capsule and injection. The oral form (capsule) of Calcitriol can be taken with or without food as directed by your doctor. The parenteral form (injection) will be given by your doctor in a hospital setting. Hence do not self-administer it. The dose and duration of treatment will be decided by your doctor based on other health conditions. Laretol Injection is recommended for use in children only if prescribed by a paediatrician. Inform your doctor about all your medications including any Vitamin D supplements and any health conditions like kidney/liver problems. Avoid drinking alcohol during the treatment with Laretol Injection as it may decrease its absorption.
